This full billet rear clutch retaining hub is made from 4140 heat-treated, stress-relieved billet steel versus the OE cast piece. The factory cast retainer is known to fail in high torsional fatigue situations such as higher line pressure, commercial use and heavy duty towing and hauling. This new billet piece is the correction you've been looking for.
For 48RE, 47RE, & 47RH transmissions only: this billet band anchor will only fit Ram 5.9L Cummins with 48RE, 47RE, or 47RH transmissions. Please verify your truck's transmission type before ordering.
